BULKHEAD.

Specification of Letters Patent.

Application filed November 26, 1915. Serial N 0. 63,606.

ported in the end of a car and liftable into.

horizontal supporting position underneath the car, the object of my invention being to provide an improved form of spring means for assisting in the lifting of the bulkhead,

the spring means being so positioned in connection with the bulkhead as to be easily attached to and detached therefrom, and being also so positioned and arranged in connection with the bulkhead and car body as to be protected from injury in the use of the car.

To this end the invention consists in the features of construction, combination, and arrangement of parts hereinafter described and claimed.

In the accompanying drawings forming part of this specification,

Figure 1 is a vertical cross section of a refrigerator car with the bulkhead and my improved spring means arranged in connection therewith;

Fig. 2 is a section on line 2-2 of Fig. 1; and

Fig. 3 is a vertical section on line 33 of Fig. 1.

In the drawings, 2 represents the car, 3 the side walls, and 4 the roof of an ordinary refrigerator car. Extending across the end of the car and having slidable support by means of pins 5 and 6 normally projecting into vertical guideways or grooves 7 in the side walls of the car, is the bulkhead or partition A of any desired openwork construction. Extending from the upper ends of the guideways 7 horizontally andv preferably downwardly toward the adjacent'end of the car are guideways or grooves'8.

For the purpose of assisting in the rais ing of the bulkhead I provide a pair of springs B positioned in parallel horizontal guideways or grooves 9 across the top of the car. The ooves 9 extend as shown in Fig. 1 from side wall toside wall, and are formed with a flooring 10 preferably of metal. Each spring, as shown in Fig. 2, is rigidly connected at one end to a bar 11 secured in the side wall of the car. Each bar 11 in the drawings is shown projecting through the side wall of the car and carries on the outer end a nut 12. The opposite end of each spring is clamped or adjustably secured to the end of a cable 13 by a suitable clamp 14. Each cable 13 runs over an idler 15 journaled in the bracket 16 secured upon the ad j acent side wall of the car. The cable thence passes over a second idler 17 journaled in a bracket 18 secured upon the side of the car, and thence downwardly alongside the bulkhead, as shown in Fig. 3. The lower end of each cable is formed with a loop 19 embracing the adjacent pin 5 of the bulkhead. In carrying out my invention I provide a pair of castings 20 secured upon opposite side walls of the car, said castings carrying the idler supporting brackets 16 and 18. By the use of the supporting castings 20 and the false bottom 10 forming the flooring for the spring, I am enabled to very conveniently and quickly support the springs B in the top of the car above the bulkhead or remove the same without in the least cutting or interfering with the body of the car. I also secure a construction and arrangement of spring particularly easy to connect or disconnect from the sides of the bulkhead and which are removed from any opportunity of being injured in the handling of the contents of the car. As will be evident, when the bulkhead is supported in raised position underneath the roof of the car, all features of my invention are in position underneath the roof of the car leaving the interior of the car entirely unobstructed.

In lowering the bulkhead it will be pushed down against the tension of the springs B and in raising the bulkhead the pull of the springs will assist the operator. The tension of the springs may be increased or decreased by adjustment of the clamping support 14, and nuts 12.

I claim:

1. In combination with a refrigerator car including an openwork bulkhead bodily movable both in horizontal and vertical positions in the car, cooperating lifting means for said bulkhead including a pair of springs anchored underneath the car roof, and a cable connection between the ends of said ipriigs and the adjacent sides of the bulk- 2. In combination with a refrigerator car including a bulkhead vertically slidable within the car, cooperating lifting means for said bulkhead comprising a pair of springs, the springs being each anchored at one end upon the car body and a cable connection between the free ends of said springs and the adjacent sides of the bulkhead.

3. The combination with a refrigerator car including a bulkhead vertically slidable within the car, pins projecting outwardly from the sides of the bulkhead, cooperating lifting means for said bulkhead including coil springs horizontally positioned underneath the car roof, anchoring means for one end of each spring, and cables connected with the free ends of said springs, the free ends of said cables being connected with said pins.

4. In combination with a refrigerator car including a vertically movable bulkhead, co-

operating lifting means for said bulkhead including coil springs positioned under the car roof, anchoring means for one end of said spring, cables connected with the free ends of said springs, horizontally and vertically disposed idlers supported upon each side wall, a cable connected with the free end of each spring, and running over the adjacent horizontal and vertical idlers, the free end of said cable depending downwardly from said vertical idler and being removably secured to the adjacent side of the bulkhead.

In testimony whereof I aflix my signature in presence of two witnesses.
